    Is (h\circ g)\circ f = h\circ (g\circ f)?

    1. Prove that (h\circ g)\circ f = h\circ (g\circ f) Homework Equations f:A\longmapsto B, g:B\longmapsto C, h:C\longmapsto D The Attempt at a Solution (h\circ g)\circ f =\{(b,d):d=h(c)\}\circ f =\{(b,d):d=h(g(b))\}\circ f I reach there and get stuck to continue...
